My hat's on the side of my head

Wales are top of the six nations, and I am on the mend. All together now:

Yesterday I was so blue
Bluer than the deep blue sea
Now I'm singing
Whistling a tune
All the livelong day
If you want to know just why
I can truthfully say;

I've got a feeling I've found her
It was something she said
She's got me walkin' on
The tip of my toes and my hat's
On the side of my head.

All my troubles are mended 
Cause she's my needle and thread 
She's got me walkin' on the 
Tip of my toes and my hat's 
On the side of my head.
